One-time backfill: gives every existing project a YEAR-DIVISION-STATE-### number using the same shared sequence as new estimates, and writes it into every screen that shows the number (proposal log, pre-ops, backlog, billing queue, closeout). Project keys, estimates, POs, and invoices are untouched. Rows with numbers already in the new format are unchecked by default; rows with old-style numbers are unchecked too, since those numbers may be printed on client documents — check them only if you want them replaced. State comes from the proposal's territory where possible; fill in any red boxes.
